Steps to Reproduce
- User was logged in and accepted an incoming call.
- Cisco server has been failed over to Side B.
- Icon in the CTI toolbar changes to connecting but agent is unable to perform any actions.
- At this point the call is being shown as ended at agent side but is still intact at customer side.
- Agent can still perform basic interaction manually.
- Cannot logout of CTI nor Interaction Portal. The screen is just stuck.
- Now failed over back to side A
- Still no response on the screen
The call from customer end also disconnects.
There have been two extra scenarios that we have tested during the fail over from side A to Side B.
a. When Side A has been failed over to side B the screen is stuck, if the agent refresh the screen, the agent is able to login into CTI once again but cannot log out of the Interaction Portal.
b. In the same scenario, when the agent login into the new session, he is able to login into CTI and Interaction Portal using the same login and carry out his work as usual.
i. Now Side B is active and Side A is down.
ii. The Agent logins into the CTI in a new session and an incoming call was placed.
iii. Same scenario as mentioned above is observed.(Points 3,4,5,6)
iv. Now the customer ends the call
v. Failed over to Side A from side B
vi. Re-connect icon appears and immediately changes to available mode
vii. Now an incoming call was made and the customer was could hear engaged tone. (this means though the agent was available no customer calls are being routed to him.)
